Energizer Hearing Aid Batteries Size 675

Energizer Size 675 Hearing Aid Batteries (Blue)

Energizer size 675 zinc-air batteries supply steady 1.45 V-class power for high-power behind-the-ear (BTE) hearing aids and select audio processors that require the 675 size. The larger can provides more capacity than sizes 13, 312, and 10, helping reduce mid-day changes during long workdays, travel, or heavy streaming.

Who Should Choose Size 675

• Use if your device manual specifies size 675 and you rely on strong amplification or frequent wireless streaming.
• Use for long, predictable runtime between changes and stable performance under higher current draw.
• Avoid if your device requires a different size or is built for rechargeable power systems.

How Zinc-Air Works

Zinc-air cells start delivering power only after air enters the battery. This chemistry offers a flat, consistent output suited to advanced features like directional microphones, noise management, and wireless accessories.

Activate and Handle for Best Life

1. Peel the blue tab completely to expose the air holes.
2. Wait about 60 seconds before inserting so the battery can fully activate.
3. Insert with clean, dry hands and correct polarity.
4. If your device uses a battery door, open it at night to reduce idle drain and moisture build-up.
5. Store sealed cards at room temperature in a dry place; do not refrigerate and do not pre-activate.

Expected Runtime

Actual life varies by device model, gain settings, streaming time, and sound environment. Use these conservative planning ranges for size 675 with all-day wear:

Usage Pattern	Typical Range	Notes
Light (little to no streaming)	14–20 days	Lower gain and quieter days extend life
Mixed (some streaming)	10–14 days	Common for high-power BTEs
Heavy (frequent streaming)	7–10 days	High current draw shortens the interval

Planning tip: If you typically change on day 10–12, set a fixed swap day every other week and carry a spare pair for events, flights, and presentations.

Stocking and Pack Size

Keep a simple buffer so you never run out. A quick rule of thumb: average days per cell × 2 × number of devices.

User Type	Suggested Stock	Why
Daily wearer	12–24 cells	Aligns changes to your calendar with cushion
Heavy streamer	24–36 cells	Covers shorter intervals and travel
Caregiver or clinic	Multi-card sleeves	Faster counts and first-in, first-out rotation

Alternatives and Compatibility

Follow your device manual. Hearing aid battery sizes use a universal color code: 10 (yellow), 312 (brown), 13 (orange), 675 (blue).

Size	Typical Devices	Relative Runtime	Trade-off
312 (brown)	RIC and mini-BTE	Shorter	Smaller, lighter form factor
13 (orange)	RIC and BTE	Medium	Balance of size and endurance
675 (blue)	High-power BTE, select processors	Longest	Larger can size

Safety and Disposal

• Keep batteries and packaging away from children and pets. If swallowed, seek immediate medical attention.
• Do not carry loose batteries with coins or keys; store in the original card.
• After use, place cells back in the empty card or tape terminals before disposal.
• Batteries are mercury-free. Follow local rules for disposal or recycling.

Troubleshooting

• New cell, no power: Confirm tab removal, wait 60 seconds, check polarity, and clean contacts.
• Intermittent sound: Ensure the battery door fully latches and air holes are not blocked by debris or oils.
• Shorter life this week: More streaming, louder environments, or new programs increase current draw.
• Battery warmth: Mild warmth can occur during heavy use. If unusually warm, power down, reseat, and try a fresh cell.

FAQ

Are size 675 batteries rechargeable?

No. Size 675 zinc-air cells are single-use. Rechargeable options require devices designed for rechargeable systems.

Why wait after peeling the tab?

Waiting about 60 seconds lets air activate the chemistry, which improves stability and practical runtime.

How long should size 675 last?

Plan for about 7–20 days depending on device, gain, streaming, and environment. Set a consistent swap routine for predictability.

Can I store batteries in the refrigerator?

No. Store sealed batteries at room temperature in a dry place to avoid condensation and performance issues.

How do I confirm compatibility?

Check the device manual and color code. Blue indicates size 675; never force a different size.
